Connecting pronouns guide the knowledge points of the subject clause

Interrogative pronouns. When it comes to generating clauses, they are all called conjunctive pronouns, who, whom, whose, what, which, whoever, whomever, whichever, whatever, a total of nine, that is, except for whose, the "-ever" suffix cannot be added, and the rest are fine. They can cause:

a.Subject clause:

it hasn’t been announced who won the prizes.Who has won has not yet been announced.

b.Object clause:

i don’t care what they think.I don't care what they think.

c.Predicative clause:

what i want to know is which road we should take.What I want to know is which way we should go.

d, adverbial clause.

wherever you go,whatever you do,i will be right here waiting for you.Whatever you go, whatever you do, I'll be here for you.

e, conjunctive pronouns can also give rise to infinitives.

are both used as objects or objects of prepositions:

lucy can’t decide which to choose.Lucy.

You can't decide which one is better.

Preposition + relative pronoun leading definite clause is a form of prepositional preposition, and there are three characteristics here:

1.When the relative substitute is the object of the preposition in the clause, the preposition is often preposed.

2.When the preposition is preposed, the relative pronoun can only use which, whom, and cannot use other relative pronouns.

3.When a preposition is preposed, the relative pronoun cannot be omitted.

The main limb of the definite clause guided by "preposition + relative pronoun" should be used in the formal style, and the preposition is usually placed at the end of the sentence in the informal style.

The relative pronoun which which is used directly after the preposition cannot be replaced with that, and the relative pronoun whom, which is used directly after the preposition, cannot be replaced with whom.

Relative adverbs when, where, why can sometimes be replaced with "preposition + relative pronoun which", depending on the situation.

In a very formal style, the definite clause guided by "preposition + relative pronoun" can be condensed into a "preposition + relative pronoun + infinitive" structure.

The attributive clause guided by the relative pronoun of a preposition.

Preposition-plus-relative pronoun-led definite clauses are mainly used in formal styles. The relative pronoun which, which is used directly after the preposition, cannot be replaced with that, and the relative pronoun whom, which is directly used as the object after the preposition, cannot be replaced by who.

English prepositions

It indicates the relationship between nouns, pronouns, etc. and other words in the sentence, and cannot be used as a separate sentence component in the sentence. Prepositions are generally followed by nouns, pronouns, or other parts of speech, phrases, or clauses equivalent to nouns that are stupid and stupid as their objects, indicating their relationship with other components.

The preposition and its object form a prepositional phrase, which is used as a preposition, a predicate, a complement, a definite or prepositional object in a sentence. At the same time, the usage of prepositions is also very flexible, the same preposition can express multiple meanings, and prepositions can be divided into time prepositions, place prepositions, mode prepositions, reason prepositions, quantitative prepositions, and other prepositions.
